Simulate DNL and INL
Not sure what method codec is refering to but i assume is a ramp test where we see where the transition from 1 bit to another occurs.
For a 12 bit ADC, 4 samples per LSB = 4*4096 = 16 384. Wont that take ages for both a ramp test or a histrogram test?
Maybe my comp is...
how to inl simulation
Is it possible to simulated DNL and INL for a 10-12bit ADC?
From what i know, to obtain DNL and INL, there is the back-to-back of ADC and DAC method and the histogram method. However, these method are normally for ADCs that are already fabricated and it will take years...
I'm currently trying to collect lots of digital data from my ADC. I need the data to conduct a histogram test. As I need to collect total data (continuous) in the region of 100,000, it is not possible to collect the data manually. Would like to ask if anyone have done it before and how did you...
adc fundamental, inl
Would like to ask if anyone have successfully obtained the INL and DNL using the histogram method by maxim? I'm still unsure how to setup the logic analyzer to obtained the data needed.
Chip Test
Dont know if this is suppose to be in this forum.
Would like to ask those how have actually fabricated an IC chip. Would like to know how did you measure the freqency response (magnitude and phase response) of an amplifier? thanks in advance.
hi borodenkov,
I'm relatively new in this. But when you say you did transient analysis and then FFT, you did it using cadence? Really like to know how you did it.
Thanks everyone. I think i got it. :) Must change the yaxis to log scale.
Thanks for all your tips.
Update: But it is only for DFT. Still cant get the continuous harmonics waveform :(
I tried using harmonicfreq and also harmonic. Wat i did was i did a transient analysis. The i add the output wavefrom into the calculator buffer. Then i chose special function harmonicfreq/harmonic. Under harmonic number, I chose any number (1-10) and i click plot. But the CIW says the wave is...
What i did was, i perform a transient analysis with an input signal of 10kHz. Then i plot of the output on the waveform window. Then i chose calculator. I selected the output wave into the calculator's buffer. Then i choose DFT under the special function. In the DFT option form, i key in from...
calculator harmonicfreq cadence
Does anyone knows how to simulate a circuit to determine the harmonics of the circuit? What simulation should i conduct ( AC, DC, PSS...etc ) in order to obtain a waveform as shown in the picture?
I'm using cadence and i'm trying to simulate the harmonics of a...
